the late Professor
Marsh devoted to searching for dinosaurs in the Jurassic and
Cretaceous formations of the West, he did not obtain any skeletons of
carnivorous kinds anywhere near as complete as these, and their
anatomy was in many respects unknown or conjectural. By comparison of
the three Allosaurus skeletons with one another and with other
specimens of carnivorous dinosaurs of smaller size in this and other
museums, particularly in the National Museum and the Kansas University
Museum, we have been able to reconstruct the missing parts of the Cope
specimen with very little possibility of serious error."

_Evidence for Combining and Posing this Mount._ "An incomplete
specimen of Brontosaurus, found by Doctor Wortman and Professor W.C.
Knight of the American Museum Expedition of 1897, had furnished
interesting data as to the food and habits of Allosaurus, which were
confirmed by several other fragmentary specimens obtained later in the
Bone-Cabin Quarry. In this Brontosaurus skeleton several of the bones,
especially the spines of the tail vertebrae, when found in the rock,
looked as if they had been scored and bitten off, as though by some
carnivorous animal which had either attacked the Brontosaurus when
alive, or had feasted upon the carcass. When the Allosaurus jaw was
compared with these score marks, it was found to fit them exactly, the
spacing of the scratches being the same as the spacing of the teeth.
Moreover, on taking out the Brontosaurus vertebrae from the quarry, a
number of broken off teeth of Allosaurus were found lying beside them.
As no other remains of Allosaurus or any other animal were
intermingled with the Brontosaurus skeleton, the most obvious
explanation was that these teeth were broken off by an Allosaurus
while devouring the Brontosaurus carcass. Many of the bones of other
herbivorous dinosaurs found in the Bone-Cabin Quarry were similarly
scored and bitten off, and the teeth of Allosaurus were also found
close to them.

"With these data at hand the original idea was conceived of combining
these two skeletons, both from the same formation and found within a
few miles of each other, to represent what must actually have happened
to them in the remote Jurassic period, and mount the Allosaurus
skeleton standing over the remains of a Brontosaurus in the attitude
of feeding upon its carcass. Some modifications were made in the
position to suit the exigencies of an open mount, and to accommodate
